With a couple of Samsung S3s, and Acer tablet, and an old Sansa m3 player all using micro USB cable connections, I've gone through quite a few cables. It seems the quality of the micro end connectors varies quite a bit. After a bit of use, some seem to wear out, in that when inserted in the device, the connection gets loose and has to be jiggled around a bit to make a good connection. This makes charging somewhat of a crap shoot in that you're never sure whether there's a good connection in place. Sensitivity to this seems to vary with the device, with the Acer tablet being the most sensitive to it, the S3s next, and the mp3 player nearly immune to it. I've bought, worn out, and discarded a number of cables over the last several years. The best cables I've found so far are Samsung-branded ones that look like this: .. picked up as a pack of three from one of those daily deal sites. They really fit snugly, and at least so far, have continued to do so, even in the Acer tablet. They're only 3 feet in length, though, and I'd like to have some 6-footers or so around the house. Does anybody have any recommendations for cables with GOOD micro USB connectors that STAY good for more than a few months?
